The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1 to fig. 2 together, the present invention provides a method for positioning an interference source of a base station, which can be implemented by an unmanned aerial vehicle 100. The drone 100 is equipped with an interference source positioning device 200. The interference source positioning method of the base station comprises the following steps:
s12: controlling the unmanned aerial vehicle 100 to travel in the target area according to a preset track;
s14: acquiring interference source signal information of at least one position point which is acquired by the interference source positioning equipment 200 and passes through in the driving process of the unmanned aerial vehicle 100; and
s16: the interfered source signal information is processed to determine the location of the interfering source.
The invention provides an unmanned aerial vehicle 100 for locating an interference source of a base station. The drone 100 is equipped with an interference source positioning device 200. The drone 100 includes a flight controller 10, a communication module 20, and a processor 30. Step S12 may be implemented by the flight controller 10, step S14 may be implemented by the communication module 20, and step S16 may be implemented by the processor 30.
That is, the flight controller 10 may be configured to control the drone 100 to travel in the target area in accordance with a predetermined trajectory. The communication module 20 may be configured to acquire the interference source signal information of at least one position point that the drone 100 passes through during driving, acquired by the interference source positioning device 200. Processor 30 may be used to process the interfered source signal information to determine the location of the interfering source.
Wherein the interference source signal information comprises the signal strength and the vector direction of the interference source signal. The interferer locating device 200 includes a detection module that detects the strength of the interferer signal. The directional antenna provided in the interferer locating device 200 may be used to detect the vector direction of the interferer signal. Furthermore, the interference source locating device 200 has a locating module. Specifically, the interference source positioning device 200 can scan each frequency point in the frequency spectrum range according to a preset frequency spectrum range to acquire the signal intensity of each frequency point and the vector direction of the signal of each frequency point, and simultaneously acquire the current GPS coordinate information of the unmanned aerial vehicle 100 through the positioning module, and send the signal intensity of the signal on each frequency point, the vector direction and the corresponding GPS coordinate information to the unmanned aerial vehicle 100, and the unmanned aerial vehicle 100 can position the position of the interference source by processing the information. The current GPS coordinate information of the drone 100 may also be obtained by a sensor (such as a GPS, a BDS, a glonness, or the like) of the drone 100 for positioning, and the sensor obtains the GPS coordinate information and then sends the GPS coordinate information to the processor 30 of the drone 100. After the interference source positioning device 200 acquires the intensity and the vector direction of the interference source signal, the intensity and the vector direction of the interference source signal are sent to the communication module 20 of the unmanned aerial vehicle 100 and forwarded to the processor 30 by the communication module 20, the processor 30 corresponds the intensity and the vector direction of each interference source signal to the GPS coordinate information acquired by the sensor, and the intensity, the vector direction and the corresponding GPS coordinate information of the plurality of interference source signals are processed to obtain the position of the interference source. The interferer signal information detected by the interferer locating device 200 may be communicated with the drone 100 by way of wired or wireless transmission communications. In a particular embodiment of the invention, the interferer locating device 200 may communicate with the drone 100 through WiFi. Of course, in other embodiments, the interference source positioning device 200 may also communicate with the drone 100 through short-range wireless communication methods such as bluetooth and Zigbee.
It can be understood that the existing interference source positioning method of the base station is generally checked by a tester by using a handheld device. However, the installation position of the interference source of the base station is usually hidden, and the interference signal environment is various and complex, so the success rate of searching the interference source by adopting the positioning method is low, and the time consumption is long.
The interference source positioning method of the base station according to the embodiment of the present invention may perform positioning by using the drone 100 equipped with the interference source positioning device 200, when the drone 100 equipped with the interference source positioning device 200 travels in a target area, the interference source positioning device 200 may detect interference source signal information of one or more location points, and the processor 30 may determine the location of the interference source according to the interference source signal information. So, adopt unmanned aerial vehicle 100 to carry out the interference source location of basic station and can lock the region that the interference source belongs to fast, can simplify the positioning process of interference source, improve the efficiency of investigation, and can effectively ensure tester's security. In addition, the data of the interference source positioning device 200 is processed by the processor 30, and the position of the locked interference source can be intelligently analyzed, so that the operation of a tester is further simplified.
Referring to fig. 3, in some embodiments, the method for locating an interference source of a base station according to the embodiments of the present invention further includes:
s111: acquiring an interference area determined according to monitoring data of a base station; and
s112: and determining a target area according to the interference area and the endurance time of the unmanned aerial vehicle 100.
Referring back to fig. 2, in some embodiments, step S111 and step S112 can be implemented by the processor 30. That is, the processor 30 may be further configured to obtain an interference area determined according to the monitoring data of the base station, and determine the target area according to the interference area and the endurance time of the drone 100.
Specifically, after an Interference source occurs in a certain area, a mobile phone communicating with a base station whose sector covers the area may have a situation of an increased call drop rate, a failure to access the network, and the like, resulting in a sudden decrease in the number of mobile phones accessing the base station, at this time, the base station may detect whether an uplink channel of the base station is normal by monitoring Interference Signal Code Power (ISCP), where Interference Signal Code Power is the monitoring data. The existing base station mostly covers three sectors, and the interfered sector and the interference strength of the interfered sector can be determined from the three sectors through monitoring the signal power of the interference code, so as to determine the interference area. The information of the interference area can be input into the control terminal 300 communicating with the unmanned aerial vehicle 100 by the user, and is sent to the unmanned aerial vehicle 100 by the control terminal 300, and the communication module 20 of the unmanned aerial vehicle 100 receives the information of the interference area, and after the processor 30 reads the information of the interference area, the target area to be driven by the unmanned aerial vehicle 100 is determined according to the interference area and the endurance time of the unmanned aerial vehicle 100. Of course, the target area may also be determined by an external device, for example, a notebook computer, a mobile phone, a tablet computer, etc. with software having a function of calculating the target area according to the interference area and the endurance are installed, the external device sends the information of the target area to the control terminal 300, the control terminal 300 forwards the information of the target area to the unmanned aerial vehicle 100, and the communication module 20 of the unmanned aerial vehicle 100 receives the information and then sends the information to the processor 30. The external device and the control terminal 300 may perform data transmission through a wired communication manner (e.g., a data line).
So, confirm the target area according to the interference zone who obtains by the monitored data of basic station and unmanned aerial vehicle 100's duration two, can promote the efficiency of interference source location on the one hand, and on the other hand can avoid the too big interference zone investigation interrupt that leads to of unmanned aerial vehicle 100 duration is limited, even unmanned aerial vehicle 100 crashes scheduling problem.
In certain embodiments, the predetermined trajectory traveled by the drone 100 comprises an "S" shaped trajectory. Wherein the "S" type trajectory comprises at least one first route and at least one second route. The length of the first route is greater than the length of the second route, and when the drone 100 has traveled all of the first routes and all of the second routes, the drone 100 traverses the target area.
Specifically, taking fig. 4 as an example, the rectangular box represents a target region having a length L and a width W. Dividing the length of the target area into n (n is a positive integer greater than or equal to 2) small segments, wherein the length of each small segment is
Dividing the width of the target area into m (m is a positive integer greater than or equal to 2) segments, each segment having a length of
Thus, the length of each first route is
Each second path has a length of
The total length of the first routes is
The total length of the plurality of second routes is
To traverse the target area by the drone 100, the drone 100 must travel all of the first and second routes, that is, the total distance the drone 100 needs to travel is
In this way, the drone 100 traverses the entire target area, and may acquire a plurality of interference source signal information during traversing the target area, and the processor 30 may process the plurality of interference source signal information for interference source positioning.
Further, referring to fig. 5, in some embodiments, the step S12 of controlling the drone 100 to travel in the target area according to the predetermined trajectory includes:
s121: controlling the drone 100 to travel along a first route and a second route; and
s122: the drone 100 is controlled to hover and spin at intervals of a predetermined distance while the drone 100 travels along the first route.
The step S14 of acquiring the interference source signal information of at least one position point that the drone 100 passes through during the driving process, acquired by the interference source positioning device 200, includes:
s141: when the drone 100 hovers and spins, at least one piece of interference source signal information of the hover position point of the drone 100 acquired by the interference source positioning device 200 is acquired.
Referring back to fig. 2, in some embodiments, step S121 and step S122 may be implemented by the flight controller 10, and step S141 may be implemented by the communication module 20.
That is, the flight controller 10 may be further configured to control the drone 100 to travel along the first route and the second route, and to control the drone 100 to hover and spin at intervals of a predetermined distance while the drone 100 travels along the first route. The communication module 20 may be configured to obtain at least one of the interference source signal information of the hovering location point of the drone 100, which is obtained by the interference source positioning device 200, when the drone 100 hovers and spins.
Specifically, please refer to fig. 2 and 4, the drone 100 starts to travel from an end of the first route as a starting point. Wherein the first route is divided into a segments, and the length of each segment is
That is, the predetermined distance has a length of
The drone 100 starts to travel along the first route from the start point, each time it has traveled
Hovering and rotating. In the rotation process, the interference source positioning device 200 carried by the unmanned aerial vehicle 100 acquires interference source signal information in each direction, and sends the acquired interference source signal information to the unmanned aerial vehicle 100. As such, the drone 100 may acquire multiple interferer signal information for use in the location of the interferer.
In the embodiment of the present invention, the hovering position point is provided only on the first route, that is, the drone 100 performs the hovering and spinning actions only when traveling on the first route, and does not perform the hovering and spinning actions on the second route. It can be understood that the second route is located at an edge position of the target area, the strength of the aggressor signal at the edge position may be weak, and if the detection of the aggressor signal is performed at the edge position, the positioning of the aggressor may not be performed with a large effect due to the weak strength of the aggressor signal, and the amount of data that needs to be processed by the processor 30 is also increased. The first route is generally located in the middle area of the target area, and the strength of the interference source signal obtained by detecting the interference source signal on the first route is stronger, which is more beneficial to positioning the interference source.
Of course, in other embodiments, the drone 100 may hover and spin during the process of following both the first route and the second route to obtain more interference source signal information, which is not limited herein.
In some embodiments, the rotation angle of the drone 100 is an integer multiple of 360 °. That is, the rotation angle of the drone 100 may be 0 °, 360 °, 720 °, and so on. Preferably, the rotation angle of the drone 100 is 360 °. On one hand, the unmanned aerial vehicle 100 returns to the state before the rotation action is executed after rotating for one circle, so that the unmanned aerial vehicle 100 can continuously run along the first route without adjusting the running posture of the unmanned aerial vehicle; on the other hand, 360 degrees of rotation of unmanned aerial vehicle 100 can traverse all directions to interference source positioning device 200 acquires the interference source signal in all directions, be favorable to promoting the accuracy of interference source location, avoid the interference source location that the less interference source signal information that probably leads to of unmanned aerial vehicle 100 rotation angle is 0 degree not accurate enough, and the too much data bulk too big problem that needs the processing of treater 30 that leads to of the too much interference source signal information that acquires when rotation angle is 720 degree.
Referring to fig. 6, in some embodiments, the step S16 of processing the interfered source signal information to determine the location of the interfering source includes:
s161: selecting a vector direction corresponding to the interference source signal when the signal intensity of the interference source signal at each position point is strongest as a target vector direction; and
s162: and determining the position of the interference source according to the target vector directions at the plurality of position points.
Referring back to fig. 2, in some embodiments, step S161 and step S162 can be implemented by the processor 30. That is, the processor 30 may be further configured to select, as the target vector direction, a vector direction corresponding to the interference source signal when the signal strength of the interference source signal at each location point is strongest, and determine the location of the interference source according to the target vector directions at the plurality of location points.
Specifically, please refer to fig. 7, when the drone 100 hovers at the hover position and rotates, the signal strength and the vector direction corresponding to each interference source signal at the hover position may be obtained according to the interference source signal information sent by the interference source positioning device 200, the drone 100 selects the interference source signal with the maximum signal strength from the multiple interference source signals, and takes the vector direction corresponding to the interference source signal with the maximum signal strength as the target vector direction of the hover position. After the unmanned aerial vehicle 100 traverses the whole target area, a plurality of target vector directions can be obtained, and each target vector direction corresponds to one position point. Thus, as shown in fig. 7, the position of the interference source can be determined according to the intersection position of all target vector directions.
Referring to fig. 2 and 8 together, in some embodiments, the control terminal 300 includes a display screen 310. The method for positioning the interference source of the base station further comprises the following steps:
s18: the drone 100 is controlled to transmit the target vector direction and the signal strength of the interference source signal at each location point to the control end 300, so that the control end 300 displays an interference source location map on the display screen 310.
In certain embodiments, step S18 may be implemented by communication module 20. That is, the communication module 20 may be further configured to send the target vector direction and the signal strength of the interference source signal at each location point to the control end 300, so that the control end 300 displays the interference source location map on the display screen 310.
Specifically, please refer to fig. 7, the interference source positioning device 200 sends the acquired interference source signal information and the GPS coordinate information corresponding to each interference source signal information to the drone 100, and the drone 100 forwards the GPS coordinate information to the control end 300. The control terminal 300 receives the interference source signal information and the GPS coordinate information corresponding thereto, processes the information by the control terminal 300, and displays the processed result (i.e., the interference source location map) on the display screen 310. The content displayed on the display screen 310 includes an acquisition position of each interference source signal information, a target vector direction of the interference source signal at each hovering position of the drone 100, a signal strength of the interference source signal corresponding to the target vector direction, and a predicted position of the interference source. Wherein the target vector direction may be displayed by an arrow; the signal intensity of the interference source signal corresponding to the target vector direction can be represented by the line length, the longer the line length is, the larger the signal intensity is, the shorter the line length is, the smaller the signal intensity is; alternatively, a specific value of the signal strength of the interference source may be marked at the arrow indicating the direction of the target vector, so as to facilitate the viewing and analysis by the tester.
In some embodiments, the control end 300 may not have the display screen 310, and the control end 300 is in communication connection with an external device, so that the display of the interference source location map is performed by means of a display on the external device. Specifically, the interference source positioning device 200 sends the acquired interference source signal information and the GPS coordinate information corresponding to each interference source signal information to the drone 100, and the drone 100 forwards the GPS coordinate information to the control end 300, and then the control end 300 forwards the GPS coordinate information to the external device. The external device processes the information and displays the processed result (i.e., the interference source location map) on a display. The external device can be a notebook computer, a tablet computer, a mobile phone and the like. The external device and the control terminal 300 may perform data transmission through a communication means (e.g., a data line) of wired connection.
The computer readable storage medium of embodiments of the present invention includes a computer program for use in conjunction with the drone 100. The computer program can be executed by the processor 30 to perform the method for locating an interference source of a base station according to any of the above embodiments.

controlling the unmanned aerial vehicle 100 to travel in the target area according to a preset track;
acquiring interference source signal information of at least one position point which is acquired by the interference source positioning equipment 200 and passes through in the driving process of the unmanned aerial vehicle 100; and
the interfered source signal information is processed to determine the location of the interfering source.
